Methods and materials for recombinant production of saffron compounds

摘要

Recombinant microorganisms, plants, and plant cells are disclosed that have been engineered to express a zeaxanthin cleavage dioxygenase alone or in combination with recombinant genes encoding UDP-glycosyltransferases (UGTs). Such microorganisms, plants, or plant cells can produce compounds from saffron such as crocetin, crocetin dialdehyde, crocin, or picrocrocin.
